Troubleshooting guide Windows does not recognize the second hard drive

This is probably the first job you should do. If not, you will end up wasting your valuable time on this matter. If your hard drive is old and has attracted a thick layer of dust or is damaged, it won’t work as it should. So, before installing it on your computer, test it.
2. See connection settings
To use the hard drive with your computer, you need to connect two different power cords. A SATA cable will be located between the motherboard and the hard drive. The second SATA cable will be located between the hard disk and SMPS or any other source where it can get Power from. If you make any errors, your computer will not be able to detect the hard drive. It would also be best if you plugged the SATA cable into the right port on the motherboard.
